Vaginal pessary

Abstract

The present invention relates to a vaginal pessary having a circumferentially closed base body which has two side wall sections, a front (anterior) wall section and a rear (posterior) wall section and wherein a central opening of the base body in a cross-sectional view transverse to the height of the base body is bounded by a closed, inner oval contour line of the wall sections. According to the invention, it is provided that the inner contour line of the wall sections is delimited by a central opening deviating from the circular shape or by an essentially trapezoidal opening with rounded edges. The special feature of these designs is that there are one or more indentations in the walls, whereby the walls adhere better to the vaginal wall and thus provide a more secure hold.

1 . A vaginal pessary comprising:
 a circumferentially closed base body, wherein the base body has two side wall sections, a front, anterior wall section and a rear, posterior wall section, and wherein a central opening of the base body in a cross-sectional view transversely to the height of the base body is delimited by a closed, inner contour line of the wall sections;   wherein the inner contour line of the wall sections has a substantially egg-shaped opening which deviates from the circular shape, or wherein the inner contour line of the wall sections delimits a substantially trapezoidal opening, the opening preferably having rounded edges with a pointed end on the anterior wall section and a blunt end on the posterior wall section and/or the contour line having a substantially elliptical shape.   
     
     
         2 . The vaginal pessary according to  claim 1 , wherein the front, anterior wall section and/or the rear, posterior wall section on the side of the opening is substantially convexly curved in the cross-sectional view, and wherein the front, anterior wall section and/or the rear, posterior wall section on the side of the opening is substantially differently convexly curved in the cross-sectional view. 
     
     
         3 . The vaginal pessary according to  claim 1 , wherein the inner contour line of the wall sections is mirror-symmetrical to a central longitudinal axis and/or to a central transverse axis. 
     
     
         4 . The vaginal pessary according to  claim 1 , wherein the base body is formed by wall sections. 
     
     
         5 . A vaginal pessary comprising:
 a circumferentially closed base body, wherein the base body has two side wall sections, a front, anterior wall section and a rear, posterior wall section and wherein a central opening of the base body in a cross-sectional view transverse to the height of the base body is delimited by a closed, inner contour line of the wall sections;   wherein the base body has a height which changes continuously in the circumferential direction, a minimum height being reached at the anterior wall section and/or a maximum height being reached at the posterior wall section and/or wherein at least one side wall section is raised relative to the anterior wall section and/or the posterior wall section.   
     
     
         6 . A vaginal pessary comprising:
 a circumferentially closed base body, wherein the base body has two side wall sections, a front, anterior wall section and a rear, posterior wall section, and wherein a central opening of the base body, in a cross-sectional view transverse to the height of the base body, is delimited by a closed inner contour line of the wall sections;   wherein the base body, in at least one side wall section, has a pocket-like deepening opened on the outside of the base body in order to form a suction or adhesion zone for adjacent tissue in an insertion state of the vaginal pessary.   
     
     
         7 . The vaginal pessary according to  claim 6 , wherein the deepening is formed on an inner side of a side wall section on the side of the central opening. 
     
     
         8 . The vaginal pessary according to  claim 6 , wherein the deepening is closed or open on an inner side of the base body, on the side of the central opening. 
     
     
         9 . The vaginal pessary according to  claim 6 , wherein the deepening on an inner side of the base body is delimited by a thin-walled wall section which has a higher elasticity and/or lower wall thickness than side wall sections adjacent to the deepening of the base. 
     
     
         10 . The vaginal pessary according to  claim 1 , wherein at least one deepening is provided in the rear, posterior wall section, wherein the receiving volume of the deepening is between 1 and 10 milliliters. 
     
     
         11 . The vaginal pessary according to  claim 10 , wherein the receiving volume of the deepening is between 2 and 4 milliliters. 
     
     
         12 . The vaginal pessary according to  claim 1 , wherein the side wall sections are substantially uniformly convexly curved on the side of the opening. 
     
     
         13 . The vaginal pessary according to  claim 1 , wherein the contour line has a continuously convex course along the opening; and
 wherein the contour line is more curved and/or convexly bent in a region of the front, anterior wall section than in a region of the rear, posterior wall section.   
     
     
         14 . The vaginal pessary according to  claim 1 , wherein the contour line has a continuously convex course along the opening; and
 wherein the thickness of the side wall sections decreases starting from a proximal outer side of the base body in the direction of a distal outer side of the base body.   
     
     
         15 . The vaginal pessary according to  claim 6 , wherein the deepening is directed radially inwards. 
     
     
         16 . The vaginal pessary according to  claim 6 , wherein the deepening is delimited on an inner side of the base body by a thin-walled wall section which is turned out inwards with respect to the side wall sections of the base body adjoining the deepening. 
     
     
         17 . The vaginal pessary according to  claim 6 , wherein at least one deepening is provided in each side wall section, the deepenings preferably being arranged opposite one another. 
     
     
         18 . The vaginal pessary according to  claim 1 , wherein at least one deepening is provided in the rear, posterior wall section, wherein an opening surface of the deepening is between 1 and 8 cm 2 . 
     
     
         19 . The vaginal pessary according to  claim 18 , wherein the opening surface of the deepening is between 2 and 3 cm 2 . 
     
     
         20 . The vaginal pessary according to  claim 1 , wherein at least one deepening is provided in the rear, posterior wall section, wherein an opening surface of the deepening has a convex and/or oval inner contour deviating from the circular shape in a side view.
